This invention relates to"devices for usein connection with window panels/erin fact movable panels of any kin'dor class adapted to be moved into `several positions in their supports, for example, inthe opening and closing of a window,and more particularly to the operation of the windows in'the several parts of a motor vehicle; and the object of the 'invention is to provide a Awindow opl0i erating device of the classspecilied employing as a window engaging or operating member, one or more rollers composed of resilient material preferably'rubber or a composition of rubber, and still furtherl to the provision l of a ribbed, tooth-like or roughened surface on the periphery of said roller or rollers adapted to be flexed and placedfu'nder compression in engaging thefwindow panel in the operation of raising and lowering the same; a further object being to provide -a device of the class described the 4operatingroller"of which serves to'maintain the window panel in different positions of adjustment `and against accidental displacement, the operating device Aincluding a backingroller also preferably composed of resilient material and preferably provided 'with a smooth-surface; a still further object being to provide a frictionally operated arm having a cushioned end adapted to normally engage one surface of the window panel and to bemoved .into a position beneath the panel when ina fully closed position to alsol aid in maintaining the panel against accidental displacement' and vibration; a further object being to provide a. cra-nk geared to the rubber drive rolleror wheel preferably through a worm gearingv to maintain the operating roller against rotation by the weight of ya window panel andy to permit of the movement of said roller only through the cranking or othermeans proview, the invention consists ina devicevof the class and for the purpose specified which is simple 'in construction, eticientv infuse, and -Which is constructed as lhereinafter described and claimed. y f W i The invention is fully disclosed in the following speciiication, of which thenaccompanying drawing formsa'part, inwlich the yand form corresponding and substantiallyV separate parts of my improvement are designated by suitable reference characters in each of the-views, and in which Fig. 1 is a cross sectional view of a part of av` window panel support showing my improved operating device mounted in connection therewith..

Fig. 2 is a sectional'plan view of the construction shown in Fig. 1.

Fig.-3 is a sectional side view of the structure shown in Figs. 1 and 2; and,`

Fig. 4 is an enlarged sectional view on the line 4--4 of Fig. 2 and'showing one of the parts in adiiferent position.-

In the drawing I have shown for the pur- 5 pose of illustrating one use of my invention,

part of a door 5 of a'motor vehicle having at its upper end portion a window opening 6, which is controlled by a window panel 7 It will be understood that my invention is not limited to this use, and my improved operating device may be employedin connection lwith window panels of any kind or class of support,` forv example on the windshield, or 7 indoors,` cabinets or the like. 5

l VIt will be understood that the panel 7 is mounted `in connection with the door 5in the usual guide grooves 8 which may be of con-4 ventional orl any desired construction.Y Mounted within 'the door below the sill 9 of the window opening 6 is one of my improved operating devices 10 which consists of two shafts 11 and v12 arranged in spaced and par allelrelation and having bearings in bracket faces 13 `disposed at the opposite end portions of said shafts,'the brackets being arranged beyond the side edges of the window panel 7 as will be apparent to permit of the :tree movement of the panel downwardly be-V tween saidbrackets asclearly seen in Figs.

i 2 and 3 of the drawing. vided; and with these and fother objectsy in V-shaped tooth or riblike projections 16 having radial walls 17 and tangentially arranged walls 18 as clearly seen in Fig. 4 of the drawing so that the members 16 are capable of flexing in the clockwise rotation of the rollers as seen in Fig. 4, and to be placed ,under compression Ain this rotation, the recesses 15 permitting the rubber in the members 16 to Viow laterally when placed under compression, insuring a tirm-and positive-em gagement with the smooth surface 'of the panel 7. V

Mounted on the shaft 12 arebacking'rollers 19 which are arranged in common alinement with the rollers 14 so as lto back up Vthe panel 7 where'the pressure'ofthe-rollers 14 lis Vexerted 4thereon preventing the possibility of cracking or breaking 4the glass panel. While the `rollers 19 are preferably composed of rubber, Athesame Amay fbe-'composed of any suitable material'fand inlay-be in fact of a solid or rigid nature-to prevent lateral displacementF orstress upon the ;panel,

and if composed of' rubber will -be of amore rigid body with Arespect `to -resiliency AJthan the body of the rollers 14.

Arrangedv on the'shaft -11 between the 'rollers -14 is a'bearingfblockQ() 'havingtwol'bearings 21 in which the shaft y11-is mounted and two Adownwardly `extending fbearings 22 in which the crank shaft 23 is mounted. Secured tothe `shaft 11 between @thebearin'gs-Q'l Aisaworm gear 24 whichmeshes-witha -worrn mounted onthe shaft 23 betweenthebearings 22. At Athe outerfend -of the shaft'23 is a 'crank lever 261by lmeansof which said shaft and vthey device as a whole 'isioperated The shaft 23 `projectsthrough vthe inner face of the'door Vand passes throughbearing members 27 securedit'othe inner face .5a of the door. Thecranklis arrangedonthe shaft 23 inwardly oftheinnerface 5a oftli'e door,

permitting of th'effree rotation ofthecrank `to operate the k'window panel. It Vwill be understood Vthat in :rotating the-crank :26 in either direction, `the :shaft 11 Twill vbe rotated through the'worm' 25:*a'ndworm lwheel 24 correspondingly rotatingthe :rollers 2145 to raise or lower the panel :7 :By'virtue ofthe worm drive, thep-anel 7 will -belmaintained `in its positions -of adjustment "against displacement in that `the rollers l14 are YVlocked against rotation'by l.virtue of such gearing.

I also ypreferably employ 'fa hook-.shaped karm 28 which Yis frictionally'supiported onfthe shaft 11, preferably fby meansof a rubber bushing V29, notefFig.4 2 ofthe drawing. The hook endof the-arm 28jisprovided withfa 'cushioned'facingBO ofvfelt, `rubber or similar material. Infth'e operation :o'f raising v'the Y panel 7, the arm 28 is moved 'inA the direction of the paneland the cushioned end 80' nor- Vmallyengages one side facevof the panelunder tension as seenfin Figs. 1 and 3 ofthe drawing. When Vthepanel has been? moved adapted to be flexed `and placed A under com-"` '-freeldownward movement, whichiscontrolled howeverbyth-e frictional and tensional enagement of the rollers 14 with said panel.

d" twill `alsoibe understood that the frictional ,engagementof the arm 28 with the shaft 11 is comparativelylight and not sufficient to exert anyexeessiye ipressure upon the ,panel 7 in fthe operation of-raising the same. Asamatteref fact, thefaImZQS-may-or. may notbeernployed.

:It will be understoodthat -my 'invention is .notne'cessarily limited to the use of two sets of Irollers 14e-f1.9*as one set o'f Y.these rollers will-be amply sufficient, especially inwerking 4upon-comp arati-vely small fpanels, and-on the may he-employed if desired when working upon wider vpanelsor the' control from a .sin- -gle operating means. yAszhereinbefore' stated, :whileI-have shown and describedoneuse of other hand, .a .-g-reater number ofthe /rollerso `.m-y .vinvention, 11am.notnecessarily.limited tofmi this uSenOram Iznccessarily limited'to lthe specifi@ details of construction lherein shown -and described, and Various chan-ges therein andlmodiieationse'thereofi-maybel made with- -inthescope ofthe appended claims without "3100 .-.comprisin-g .a driven "roller .mounted vrto engageoney side face of said panel, 'theperiphferyfofsaid :roller having projecting bodies .-ad-aptedto be plaeed'under compressionl in eni gaginfgthe panelitobe operated fand yfor lsupporting fsaid lfpanel f. against "movement V`in its different Ypositions Lof adjustment, a backing -elementdisposed onntheoppositeside of said epos :panel and infalinement with saidroller, means' z 5 .inyolving-a worm'and worm wheel-forA actuatingA said -.roller, and -for preventing the .rota- .tion ofsaid roller-.and'shifting yof said panel when saidlastnamedmeansis at rest, a crank for rotating said worm, Vand other meansop- .erated through said worm YKand worm 4wheel :andadaptedito cooperate with said-panelto 'aidin supporting'the panel in closed position.
